Specification forming part of Letters Patent No. 212,172, dated February11, 1879; application filed August 2, 1878.

To all whom it may concern:

Be it known that I, MOSES J. BARRON, of San gamon county, in the Stateof Illinois, have invented certain new and useful Improvements inCheck-Rowers for Corn-Planters; and I do hereby declare that thefollowing is a full,

clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the construction and arrangementof a check-row attachment for corn-planters, which is easily adjusted,simple and cheap in construction, and reliable in operation.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, whichform a part of this specification, and in which Figure l is aperspective view of my improved check-row attachment. Fig. 2 is aperspective view of the device for attaching the check-rower to theplanter-frame. Fig. 3 is a perspective view of the center mechanism fortransmitting the vibratory motion. Fig. 4 shows the bar connecting thelevers or cranks of the yokes or forks. Fig. 5 is a perspective view ofthe yoke and crank.

A represents the main bar of the checkrower, carrying the entiremechanism, and to be attached to the planter-frame by means of fastenersG C. These fasteners are constructed as shown in Figs. 1 and 2, eachhaving top and bottom slots or recesses, a a, at right angles to eachother. The bar A rests in the top recesses, a, and is fastened bysetscrews 2), and the fasteners are placed with their bottom recesses,a, over suitable bars of the planter-frame, and fastened by set-screwsb. By this means the check-rower can be easily adjusted to any planter.

At each end of the beam A are mounted two grooved pulleys, B B, whichturn upon vertical pivots in a metallic frame, R, and are placed at sucha distance apart as will allow the knotted rope M to pass freely betweenthem. The lower plate of the metallic frame It forms a guard below thepulleys, to prevent the rope from falling from its place, while theupper plate of said frame is divided, and forms projections O, toprevent the rope from slipping off.

At a suitable distance from each end of the bar A is mounted a shortshaft, (1, across the bar in suitable bearings, and to this shaft issecured the yoke or fork L, through which the rope passes. This yoke orfork is constructed substantially as shown in Fig. 5, it being split atits upper end for the insertion of the rope, and the slot 0 in the yokeis made larger at the top than at the bottom, the lower end of said slotbeing just large enough to allow the rope to pass freely, but not theknots. Hence, as soon as the knot strikes the yoke it is thrown down toone side in an inclined position, and the knot slips up into the upperlarger portion of the slot 6 and passes through the same.

The yoke is, on each side, near its lower end, provided with aprojection, f, to prevent it from being thrown too far either way, saidprojections acting as stops against the bar. At the upper end of theyoke, where it is split for the insertion of the rope, the two arms passor overlap each other, and thus prevent the rope from slipping out. Eachshaft d forms at one end a crank, P, and the two cranks point inopposite directions, as shown, and are connected by means of a bar, K,placed upon their ends.

From the center of the bar A projects an arm or rod, N, upon which ishung an inverted stirrup, H. The inner arm. of this stirrup is formedwith a longitudinal slot, J, through which passes a pin, I, projectingfrom the connecting-rod K. This pin plays freely in the slot J as therod K is moved by the cranks of the yokes, by means of which anoscillating motion is given to the stirrup H. On the other arm of thestirrup is an adjustable clamp, G, fastened by means of a set-screw, h,and to this clamp is attached a rod, F, for connection with the drop-barD of the planter. The rod F has at its end a clamp, E, to be adjusted onthe bar D and fastened by a set screw, 'i.

It will readily be seen that by means of the various adjustments, asdescribed, the checkrower is adapted to be used on any kind of planter.

The check-rower being fastened firmly to the planter and the checkropeproperly adjusted, as the team moves forward the rope passes through thepulleys and strikes the yokes, causing them to turn from side to side,and moving the rod K, with its pin I, in such a manner as to cause thestirrup H to move the rod F, and give to the drop-bar D a regularbackward and forward movement, which results in opening and closing theholes beneath the seed-corn in the boxes at regular intervals.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is
